as above, im helping 2 mates swap engines.
1 has a 4x4 saph on a j plate
the other is a 3dr on a d reg.

can we just take both engines out, swap exhaust manifolds, sumps, inlet plenum covers(with fuel rails and regulators) and mounts
and bolt them in the other car.
and i was going to keep the engines, looms and ecus together still.
is this ok?

or does the 4x4 loom and ecu need to stay in the 4x4 car?

and other than the sumps inlet and exhaust is there any thing else i need to swap? or any other parts i will need when doing the swap?

just thought water pumps are different to, do these need to be swapped?
i guess it would be easier
cheers
